Specification of `Letters Patent.

Serial No. 664,494.

To all 'whom it may concern:

Be it known that I, EVERETT P. ALLEN,

a citizen of the United States, residing at Chicago, in the county ofCook and State of Illinois, `have invente'd a certain new 4and usefulImprovement in Siphon-Valves,

vof which the following is a specification.

My invention relates to siphon valves, and

khas for its object to provide a new and improved valve of thisdescription. p y invention is illustrated in the accompanying drawings,wherein- Figure l is a view of the valve; Fig. 2 is alongitudinalsectional view of the valve of Fig. l showing it connectedto the radiator.

I have shown my invention .as applied lto a valve adapted to be used inconnection withsteam `heating systems. As herein shown t-he valve has anouter casing A. Within said'casing is a valve chamber B containing ailoat valve C. The chamber B is connected by the connecting piece D withthe heater. A passageway 'E' leads from the chamber B to the tube vE1,and communicatespwith the atmosphere. Said tube E1 passes .through thechamber F. The chamber B is connected with the chamber F by theconnection G. The valve C is a float valve and is operated by means ofwater or the like, the parts arranged so that when the water reaches apredetermined height t-he valve will be floated so as to move the partC1 so astostop the passageway E.l When the passageway E is open the airfrom the heater vpasses out there-- through and through the tube E1 tothe atmosphere. When the steam passes through the tube E1; itL heats thechamber F and the air thereiinthus forcing the water down into thechamber B so as to float the valve C and close the passageway E. Asiphon device' is connected with the valve, said Siphon deviceconsisting of twoparts H and I. The part H is fastened in position inany desired manner, as by solder, and 1s preferably arranged at -the topofthe connecting piece D, one branch proj ecting. down into the chamberB. If desired, an oifset,

50 as shown at H1, may be made in the chamber B for the end of the partH. The part I is inserted in the heater andthe end thereof projectsbelow theendf of the part H so that a Siphon effect is produced, The

parts H and I are adjustably connected Vtogether so that they may berotated with relation t0 each other, and so that the bent ends thereofmay be spread apart or moved closer together by sliding one telescopingpart within the other. These results may be secured inlany desiredmanner as, for example, by making one of the parts t into the other withla tight fit which will prevent leakage, but which will yet permitrotationand longitudinal movement.

' I have described in detail a particular construction embodying myinvention, but it is of course evident that the partsmay be varied inform, construction and arrangement, and I therefore do not limit myselfto the particular construction shown.

' The use and operation of myu invention are as follows: In attachingthe device vto the heater the part I is first inserted in the opening inthe heater adapted to receive y,the

D is then inserted in said opening and the valve is then "rotated soasnto cause the screw.- threaded connecting piece D to be forced intothe opening. I During this operation the part I being in the radiatorcannot rotate, but because of its connection with the part H the valveand the part H can be rotated. In view of the relative longitudinal.movement of the parts H and I they can slide longitudinally withrelation to each other so as to adjust themselves to the conditions ofuse'. After the device is in position and the system is started up, theair from the radiator passes through the passageway E and tube El,

air. When steam 'passes through the tube El it heats t-he atmosphere in'chamber F and forces the water into chamber B raising the valve to closepassageway E. When the radiator is shut or the system shut down the airin the chamber F is producing a partial vacuum, thus drawing up thewater from the chamber B into the chamber F and causing the loat valveto lower so as to open the passageway E, thus bringing the parts intoproper position to permit the escape of the air when the radiator isthen turned on. The parts are arranged so that the valve C will befloated and raised to its proper position before the level of the waterin the vchamber B reaches a sufficient height to cause the Siphon to act,

cooled and contracts,

connecting piece D. The connecting piece Y and then into the into theradiator. The importance of this siphon arrangement will be seen byconsidering, for example, the situation where the valve contains such anamount of water that when the chamber F has dra-wn all that it can drawinto it there ais still so much water in the chamber B as to cause thevalve C to float, thus closing the aperture E. Under these conditions itwill be seen that the valve becomes inoperative, for no heat can pass upthrough the passageway E so as to eX- pand the air in the chamber F andcause itv to force water out. This condition would occur, for example,when the radiator becomes flooded or under other conditions which lillthe chamber B while the chamber F is cold. The 'Siphon is so adjustedthat when the abnormal conditions are present a sufficient amount ofthewater will be drawnV off to put the valve in operative condition.

It will be noted thatwhen the parts are assembled, the two telescopingparts of the siphon may be moved longitudinally so as to vary thedistance between the siphon legs. It will further Ibe noted that eachleg is provided with an angular piece and that these two angular piecesbetween the legs are telescoped, and are free not only to rotate but tomove longitudinally.

Y 'I claim:

1. The 'combination with an air valve of a ,Siphon for drawing waterfrom said valve under predetermined conditions, said Siphon passingthrough the valve inlet and having two relatively movable parts free tomove longitudinally when the parts are assembled so as 'to vary thedistance between the legs of the Siphon.

2. The combination withy a valve for heating systems of an adjustableSiphon passing through the valve inlet adapted to ldraw water from thevalve under predeter'mined'conditions and comprising two telescopingparts between the legs of the Siphon, so that they may be spread apartwithout`disconnecting them.

3. The combination with a valve of a silpredetermined conditions,

phon passing through the valve inlet adapt# ed to draw water therefromunder predeter- 'i mined conditions, lsaid Siphon comprising two partsadjustably connected together when the parts are assembled in theiroperative relation so that the may be rotated or movedlongitudinallywith relation to each other.

4. A valve for steam heating systems comprising a. chamber, a fioatvalve therein, a

passageway controlled by said float valve,

means for introducing liquid into said chamber under predeterminedconditions to fioat the valve, an adjustable Siphon passing through thevalve inlet connected with said chamber for drawing oif the Water-underpredetermined conditions having two telescoping parts by means of whichthe legs of the Siphon are adj ust-ably connected together.

5. A valve for steam heating systems comprising a chamber, a ioat valvetherein. a passageway controlled by said `float valve, means forintroducingv liquid into said chamber under predetermined conditions tofloat the valve, an adjustable Siphon passing through the valve inletconnected with said chamber for drawing oli' the water underpredetermined conditions, said Siphon comprising two parts at an angleto the legs of the Siphon and connecting them, Said parts movablyconnected together so that LVthey may be rotated and movedlongitudinally with relation to each other.

' 6. The-combination with an air valve of a Siphon for drawing watertherefrom under predetermined conditions, said Siphon passingthrough thevalve inlet and Ahaving two le s anggl'e thereto, said latter partsworking the one within the other, so that the distance between the legsmay be varied.

7. The combination with an air valve of a siphon for drawing watertherefrom under said siphon conlsisting of two pipes bent at rightangles and telescopically joined together, said Siphon passingthroughthe Valve inlet.
